Affects SMG
ICD: CD:
[Active]: Fires a special grenade, applying 3 layers of Corrosion to targets within a radius of 2.5 units, and an additional 2 layers to the main target of the grenade. After using the skill, chance of applying Corrosion on normal attacks increase to 100% for ($duration) seconds. [Passive]: Normal attacks have ($cor_chance)% chance to apply 1 layer of Corrosion. When an enemy accumulates 5 layers of Corrosion, it deals ($cor_dam)x damage and stuns for ($cor_stun) seconds in an extremely small area, and clears the Corrosion effect on the enemy. [Corrosion]: Reduce the target's rate of fire and movement speed by ($cor_debuff)% for ($duration) seconds.
While ADS has fairly lackluster base stats that fall far behind other grenadier ARs, her job was never to deal massive AoE damage like M4 SOPMOD II or 416. She is an incredibly unique AR whose kit revolves around her Erosion status effect and the potentially insane single-target crowd control it provides.
ADS applies Erosion to all enemies she hits with Storm Surge. Erosion itself is a minor RoF and move speed debuff, but reaching 5 stacks of Eroson will stun the enemy for 2.4s and cause them to explode for 6x damage in a very small AoE (read: will pretty much hit her primary target only).
Storm Surge itself will always apply 5 stacks to the main target, causing an immediate stun and AoE explosion. Other units in the blast radius get 3 stacks and will explode after two more Erosion procs from ADS.
Because Erosion stacks are applied on a per-hit basis, players wanting to maximize the CC effect will want to improve ADS's Rate of Fire with tile buffs when possible, preferably to at least 94 (>21% RoF) or 100 (>28% RoF) to effectively stun a single enemy unit for a minimum of 7.2 straight seconds after her Skill activates.
This comes from her Grenade (2.4s) and two rounds of 5 attacks with guaranteed Erosion (4.8s) during her Skill buff
Since Elites and Bosses resist stuns, the stun niche is not always useful - pick your fights carefully!
ADS provides unparalleled single-target CC that can even bring Goliath Plus to its knees. She can even stun Hydras and Doppelsoldners as long as they are stopped at least once to remove their Elite flag.
ADS stats don't compare favorably to other AR Grenadiers, causing her DPS to fall behind her 5-star peers.
ADS's 5-stack Erosion proc AoE has a radius of 0 units, meaning it will only hit stuff whose hitbox directly overlaps the center of her target (effectively 0.4 units).
Since bosses cannot be stunned and only have one Dummy Link, ADS performs poorly against them like most other AR grenadiers.
